The rule "Okta: Profile Updated" is designed to detect updates made to user profiles within Okta, a widely utilized identity management platform. This detection leverages application log events that signal when a user's account profile is updated. Specifically, it targets the 'user.account.update_profile' event type, which is critical for identifying potential unauthorized changes that could indicate malicious activity such as privilege escalation or account creation. The Splunk logic gathers relevant fields including timestamps, source and destination users, IP addresses, and geographical data, allowing for a comprehensive view of the activities surrounding the profile update. By aggregating this data over one-second intervals and counting unique destination users, the rule helps in identifying patterns and potential anomalies in user account behavior.
